Abstract

In this study, two-dimensional numerical approach is used to analyse flow and heat transfer in the gas slider air bearing. The flow field of a micro scale channel between an inclined slider and a moving bottom wall is calculated under a variety of slider postures. The heat transfer through the channel is also calculated with variety bottom wall speed. The effects of the variable inclined angles of the slider and the variable bottom plate velocities of the channel on pressure distributions profiles are presented. The relationships of the peak pressure and windward angle, and the positions of the peak pressure along the channel are also obtained. The effects of variation in pitching angle of slider bearing on a two-dimensional heat analysis are further investigated. In this analysis, the highest pressure is obtained when the inclined angle is between medium to high cases. The location of peak pressure found to be located at 0.95 of Xc/L. The highest temperature is obtained when the inclined angle is at low. The peak temperature is located near the end of the channel for all cases. In the variable bottom wall velocities problem, both the highest pressure and highest temperature is obtained when the velocity is high respectively. With the increment of pitching angles by 0.002 rad., the outlet temperature decrease by 4.09%.
